Tether Technologies

The New Force of Certainty in Key Control

Tether Technologies' GRAVITY is the first and only industrial-grade, digital tethering solution that automatically preempts master key separation and loss - with absolute reliability. Now you can rest assured of never having to experience a card/key loss event and its costly aftermath.

Never Risk Losing Master Keys or Access Cards Again

GRAVITY doesn't find access cards/keys, because they are never lost in the first place. GRAVITY tethers your cards/keys by using an electronic signal that works as a 5-7 step, mobile barrier around the worker. Upon breaching this radius, GRAVITY’s unique alarm, vibration and strobe light are triggered.
